摘要
采用火焰原子吸收法测定了空气与废气中铅尘和铅烟气溶胶中的铅。对四种消解方法作了比较。讨论了酸度及样品基体干扰影响。测定结果令人满意。铅的检出限为0.05mg/L,线性范围0.5-10.0mg/L,采样效率为98%,样品回收率为92.3%。
The lead in aerogel samples of air and waste gas was delemined by flame atomic absorption spectrophotometry. Four digestionmethods are compared. The interferences of acidity and sample matrix are discussed. The measurement results are satisfactory. The rangeof linearity is 0.5-10.0 mg/L with detection limit of 0.05mg/L. The sampling efficiency is 98% and the recovery is 92.3%.
